The borscht and caviar will be washed down with vodka Thursday night at the annual RAJE (Russian American Jewish Experience) gala at Guastavino’s.

The Brighton Beach-based charity is paying homage to the traveling exhibit “Lives of the Great Patriotic War: The Untold Story of Soviet Jewish Soldiers in the Red Army During World War II,” a project of Odessa-born Len Blavatnik and his younger brother Alex. It’s now on display at the University of Southern California.

Len — whose $16 billion holdings include Warner Music — just returned from Cannes, where he made the high bid of $15 million for “Gone but Not Forgotten,” the gilded mammoth skeleton by Damien Hirst.
